Bug ID: 25973
Summary: basic_string::assign(InputIt, InputIt) doesn't provide
the strong exception safety guarantee
Product: libc++
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: rs2...@gmail.com
CC: llvm-bugs@lists.llvm.org, mclow.li...@gmail.com
Classification: Unclassified
Per [string.require]/2:
If any member function or operator of basic_string throws an exception, that
function or operator shall have no other effect.
libc++'s implementation of assign(InputIterator, InputIterator) does clear()
followed by push_back() in a loop, which clearly doesn't meet this requirement.
